In the title salt, (C5H14N2)[FeCl4(H2O)2], the FeII cation is coordinated by four Cl- anions and two water molecules in a distorted octahedral geometry. The piperazine ring adopts a normal chair conformation. Intermolecular N-HCl, N-H(Cl,Cl) and O-HCl hydrogen bonding is present in the crystal structure.
